The evolution of molecular catalysis science benefited greatly from the use of nanomaterials synthesis since most catalysts are nanomaterials with sizes in the 1-10 nm range. At the same time instruments were developed that can be employed to study catalysts under reaction conditions to monitor the dynamic changes that occur during catalytic reactions, their atomic and molecular structure, and composition and oxidation states with high spatial and time resolution. Discoveries included the size and shape dependence of turnover rates and product selectivity and other kinetic variables, the importance of oxide-metal interfaces in heterogeneous catalysis and the dominance of covalent bond and charged ion chemistry in transition metal and acid-base catalysis. Below 2 nm the metal nanoparticles have electronic structures that stabilize charge states, which can be used to heterogenize homogeneous catalysts. Enzymes can be immobilized on a DNA to aniline functionalized glass and they maintain most of their catalytic activity in this mode. Our aim is integration of the three fields of catalysis, heterogeneous, homogeneous, and enzyme by developing hybrid systems and new instruments that permit studies of increased catalytic complexity
